I spent about an hour reading about different head harnesses before trying this one. I have been using it for a few weeks, and I am very happy with it. It is well padded with foam rubber covered in cloth, and the padding is about 1/2 inch thick, so it does not hurt or damage my skin to use it. The hardware is sturdy, including the clips that connect the chain to the part that fits on your head. I use weight plates that have three holes around the sides of them to make it easy to pick up the plates with one hand. These holes are larger than the hole in the middle of the plates. The clips on the ends of the chain are so large that they would not go through the hole in the middle of the plates, but this is not a problem because of the larger holes. But if you are using the old-fashioned plates that have only a hole in the center (and I'm not talking about Olympic plates with a large center hole), you may not be able to thread the chain through the hole in the center of the plate.

A head harness like this makes it easy to work your neck muscles in a way that seems impossible using any other technique. Within a few weeks, my neck has become significantly stronger, and this has practical value because it is improving my posture and making it easier to look over my shoulder when I back out of the driveway. I do not expect to develop a large neck, and it's not my goal to do that. I just want to have a reasonable amount of fitness throughout my body, and this harness makes it easy to have a reasonable amount of strength in my neck.
